We present here the detection of a planet orbiting around the F6V
star HD 33564. The radial velocity measurements, obtained with the
ELODIE echelle spectrograph at the Haute-Provence Observatory,
show a variation with a period of 388 days. Assuming a primary
mass of 1.25 
, the best Keplerian fit to the data leads
to a minimum mass of 9.1 MJup for the companion.
